The aim of this study is to investigate the effect of a supplemental jump training program (added to a warm up) conducted on either sand or hard surfaces on the landing and jumping ability of young female football players. The jump training program (intervention) will be carried out twice weekly for a period of 6 weeks. Participants will be randomised (computer package will decide) into one of 2 groups (either sand training or land training). The landing ability and jumping performance of all participants will be measured both before and after the 6 week jump training intervention. It is hypothesised that supplemental training on both sand and hard surfaces will improve landing ability and jumping performance. It is also hypothesised that sand will be equally as effective as a hard surface for improving jump landing ability but may be less effective than a hard surface for improving jumping performance.
